Watershoe cake is a Cantonese snack, steamed with water and water mixed with water chestnuts. Among them, the water chestnut cake steamed with Datian water chestnut powder has a particularly unique flavor. Datian water chestnut powder is made from high-quality water chestnuts. Guangdong water chestnuts are divided into two categories: sweet water chestnuts and water chestnuts. Sweet water chestnuts are used for fresh food and canning, while water chestnuts are mainly used for cooked food or processed water chestnut powder. Water chestnuts are mostly planted in low-lying and muddy paddy fields or shallow ponds. They have less water, more starch, and a bland taste. In the old days, Datian Village was once rich in horseshoes, and later a horseshoe powder factory was opened. Due to the huge demand, horseshoes were mainly produced in Qingyuan, Fogang, Conghua and other places. The water chestnuts are processed into powder at the Daejeon Water chestnut flour factory and then shipped to various places to make water chestnut cakes. Most of the water chestnut powder used in star hotels, hotels and time-honored restaurants such as White Swan Hotel, China Hotel, Garden Hotel, Oriental Hotel, Panxi Restaurant, etc. is produced in Datian Village. Now Datian water chestnut powder is not only a specialty of our district but also of Guangzhou City.
